<b>Description(db dup)</b>
<p>The <i>dbc</i> <b>dup</b> command duplicates the cursor, creates a new cursor
that uses the same transaction and locker ID as the original cursor. This
is useful when an application is using locking and requires two or more
cursors in the same thread of control.</p>
<p>The options are as follows:</p>
<br>
<b>-position</b><ul compact><li>The newly created cursor is initialized to refer to the same position
in the database as the original cursor and hold the same locks. If the
<b>-position</b> flag is not specified, the created cursor is
uninitialized and will behave like a cursor newly created using the
<i>db</i> <b>cursor</b> command.</ul>
<br>
<p>The <i>dbc</i> <b>dup</b> command returns 0 on success, and in the case of error, a Tcl error
is thrown.</p>
